Create AAB File in Flutter | App Bundle Error Fixed | Keystore Not Found & bundleRelease Signing

Hi, Welcome to the channel,
In this video, I provide a complete step-by-step guide on how to create an Android App Bundle (AAB) file in Flutter for Google Play Store submission.

If you are a Flutter developer preparing your app for release, this tutorial will walk you through the entire AAB generation process, including signing configuration and common mistakes to avoid.
🔹complete guide and required configuration and commands
command for the ketool key generation:
keytool -genkey -v `
-keystore android\app\upload-keystore.jks `
-storetype JKS `
-keyalg RSA `
-keysize 2048 `
-validity 10000 `
-alias upload
the key alias you can change it but better to keep it same
creat the file key.properties in android folder
storePassword=password
keyPassword=password
keyAlias=upload
storeFile=upload-keystore.jks //or enter the path where the keystore file saved
Add this in app level build.gradle file
import java.util.Properties
import java.io.FileInputStream
plugins { // at the top of the file

def keystoreProperties =new Properties()
def keystorePropertiesFile = rootProject.file("key.properties")
if (keystorePropertiesFile.exists()) {
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}//add this after the plugin{


signingConfigs {
release {
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile file(keystoreProperties['storeFile'])
storePassword keystoreProperties['storePassword']
}
} //add this after the defaultconfigs{


buildTypes {

release {
signingConfig signingConfigs.release
minifyEnabled true
shrinkResources true
}

}//add this after the signingconfigs{



after this run the commad
flutter build appbundle
